Think about how many hours you spend on the web every day. Since I work from home and do a lot of web-based research, plus many of my leisure activities involve being online, I can easily clock in 6–8 hours of web browsing on any given weekday. For you, 2–3 hours might be more the norm.

Still, that adds up to a lot of hours over time. Now think about how “efficient” you are when it comes to web browsing: 10 seconds to copy text to Evernote, 30 seconds to open up Dictionary.com and query a definition, a few minutes to find online coupon codes, etc. All of that adds up too.

You’d be surprised how many hours you waste every year through inefficient web browsing, which is why you need these time-saving Chrome extensions. They’ll help you reclaim those lost hours one click at a time.

1. Hide All Tabs With a Single Click

Imagine you’re slacking off at work and you’ve opened dozens of new tabs over the last half hour, but then your boss shows up and you can’t let him see. Instead of closing them all by spamming the Ctrl + W shortcut, you can just click the Panic Button icon (or press F4) and all tabs will be closed and saved as bookmarks.

And that’s the great thing about it: When the panic situation is over, you can restore all closed tabs back to the way they were. So convenient, and I’m sure you can think of many other situations when such an extension could come in handy.

2. Automatically Find and Apply Coupon Codes

The next time you’re shopping online, whether for clothes, office equipment, gaming gear, or even just a pizza, there’s a good chance that Honey will save you a good chunk of money on your final order. Over the course of a year, it could save you hundreds or even thousands of dollars.

It’s very simple: When you’re about to checkout, click the Honey icon and the service will automatically search the web for any applicable coupon codes, test them all to see which one results in the most savings, then automatically apply it. Way faster than doing it by hand!

3. View Historical Pricing Data While Shopping

One of the downsides of shopping on Amazon is that the sticker price can be misleading. It usually shows a Was price above the Current price, making it seem like you’re getting a deal, but this is rarely the case. The Was price is just the recommended retail price when it was first released. That price could be severely outdated.

So how can you check if an Amazon price is actually a deal? Use the CamelCamelCamel website to see the item’s pricing history. If it’s below average, then yes, it’s a deal. But you can save even more time by using The Camelizer, an extension that shows this pricing history with one click.

The good news is that there are some who are doing their best to fight this, such as ReviewMeta. This site pulls all of the reviews on a product, analyzes each one for markers that might indicate fakeness, and then uses only the genuine reviews to calculate an adjusted rating. With this extension, one click is all you need to see the “real” rating of an item.

5. Save Articles to Read Offline

If there are significant chunks of time every day where you don’t have internet access, you can maximize your online time by saving articles to read later during those offline hours (such as when you’re commuting on a train or awaiting an appointment).

This may not seem like a huge time-saver, but it’s one of those things that you have to try for yourself to really get a sense of how convenient it is. You don’t have to keep Evernote open. You don’t have to juggle multiple tabs or windows. Just browse, click, and keep browsing. Excellent for when you need to research a topic and you want to compile a bunch of data very quickly.

7. Mouse Over Images to Preview or Enlarge

I know this has happened to you before: either you’re browsing a page and come across a tiny image that you have to click to enlarge, or you come across a text link to an image that you need to click to view. Not only are these annoying, but they can waste valuable time.

That’s why Imagus is such a beloved extension. With it, you can just hover over an image or link and see the full-sized result right away. No need to open a new tab and wait for the image to load. It supports thousands of sites on the web and you can customize it a bit with regard to preview size, hover delay, opacity, etc.

8. Mouse Over Words for Definitions

Whether you’re learning English as a new language, combing through tons of sophisticated academic articles, or simply trying to expand your personal vocabulary, Google Dictionary is an excellent extension to have installed. With it, definitions are never more than a click away.

Even if you’re just a regular Joe Schmoe who wants to stay up-to-date on topics like world affairs, tech news, or the realm of finance, you may regularly come across articles in Fortune or Time or Harvard Law Review that stretch your word bank. It’s nice to have this extension at the ready.

9. Highlight to Translate Text

The internet has done more for globalization than any other advancement in the history of technology, which is why the Google Translate extension is so fitting. Now you can read any article or segment of text even if it isn’t written in a language you personally know.

Just highlight a word or a paragraph and the extension can translate it in a pop-up window, no need to open a new tab or navigate to another page. Or if you want to translate the whole page, you can just click the Translate icon. The entire web is now at your fingertips.

11. Check Grammar While You Type

Most browsers have built-in spell checkers, but built-in grammar checking is rare. And it’s not like grammar checkers are only useful for those who don’t have command of the English language — even the most eloquent writer makes mistakes. Grammar checkers are great for catching those mistakes.

The thing is, emojis are a lot easier to type on mobile devices than on computers. The good news is that Emoji Keyboard can bridge that gap for you, at least within Chrome. It supports emoji searching, copy and pasting, as well as auto-insertions.
